Application filed February 15,1898. Serial No. 670,350. (No model.)

T at whom it may concern:

Be it known that 1, CHARLES F. LORD, of

Mechanic Falls,in the county of Androscoggin 7 and to that particular class of such punches as are adapted to punching a series of holes in the quarters of lace-boots for the reception of eyelets or lacing-studs; and it consists in certain novel features of construction,

arrangement, and combination of parts,which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which my invention is clearly pointed out.

Figure 1 of the drawings is a plan of a machine embodying my invention. Fig. 2 is a front end elevation. Fig. 3 is a side elevation. Fig. 4 is a sectional elevation, the cutting plane being on line 00 a; on Fig. 1. Fig.

2 5 5 is a vertical transverse section through one pair of the punching arms and tools on line y 3 on Fig. 4. Fig. 6is a plan of the adjusting-plate for regulating the distance apart of the several punches.

In the drawings, A is the bed or base plate of the machine, having formed in one piece therewith or secured thereto the uprights A, A and A B is a table secured upon the upright A 3 5 and having out through it the slot B for the passage of the punches, as shown in Figs. 1 and 4.

C is the driving-pulley, having firmly secured thereto the pinion D and mounted 4o loosely upon a stud set in the ear A projecting upward from the base plate A, said pin-' ion engaging with the teeth of the spur-gear E, loose on the shaft F, mounted in bearings in the uprights A A and having firmly secured thereon justinside of each of said bearings an eccentric G, upon which is mounted the lower end of an eccentric-rod H, the upper ends of which eccentric-rods are connected together by the rod II, as shown in Figs. 1, 2, and 4.

The upright A has secured to its upper edge the rearwardly-projecting flange-plate a, having its upper surface serrated, and has formed therein a series of slots 1), above each of which is mounted a plate 0, having its un der surface serrated to engage the serrated surface of the plate a and provided with a perforation for the passage of the pivot bolt d, which is screwed into the rear end of the arm I, which rests upon the plate 0, said pivot. pin or bolt cl being provided with the clamping-nut d and the check-nut 61 as shown in Figs. 3 and 4.

The arms I are provided at their rear ends with the upwardly-projecting branches 1 and 65 rest upon and are pivoted to the plates 0 at their rear ends and rest near their front ends upon the upright A and have set in their front ends the tubular cutting-punches e, as

shown in Figs. 4 and 5.

J J are arms pivoted to the branches 1 of the arms I, having adj ustably set in their front ends the downwardly-projecting anvil-blocks f, against which said punches 6 cut, and said arms J are each provided with a slot g, ex tending longitudinally thereof, through which the rod I-I passes, so that when the shaft F is revolved the arms J will be moved about their pivotal connections to the branches I to raise and depress the front ends of said arms J and their anvil-blocks f.

Beneath the table B and between it and the front ends of the arms I is fitted in suitable guideways the plate L, provided with a series of diverging slots h it, through which the punches 6 project, and also with the slot 71, through which the bolt 2', fixed in the table 13, projects, and is provided with the clampingnutj to firmly clamp said plate in its adjusted position, said plate being moved outward or 0 inward to vary the distances between the punches e by means of the lever M, pivoted at 7c to the under side of the table 13 and engaging a pin Z, set in the under side of said plate, as shown in Figs. 1 and 3.

The shaft F has firmly secured thereon, just outside the right-hand upright A one member N of a clutch, provided with the shoulder m, the cam-surface m, and the radial socket m and the gear E has formed thereon or se- :00

cured thereto the other member N of said clutch, provided with the shoulder 71, arranged to engage the shoulder m to revolve said shaft F, and with the circumferential groove 91, with which the shipper-fork O, secured to the shipper-rod O, engages, as shown in full lines in Fig. 2 and in dotted lines in Fig. 3.

The rod 0' is mounted and movable endwise in suitable hearings in the uprights A A and is surrounded, between the right-hand upright A and the collar 0, by the coiled spring I, the tension of which tends to move said rod 0, the shipper O, and the gear E toward the left of Fig. 2.

The shipper-fork O is formed from a plate of metal and has three right-angle bends, thereby giving to it two vertical sections and two horizontal sections parallel to each other, and is secured to the rod 0 by the vertical section connecting the two horizontal sections, as shown in Fig. 2.

R is a locking-bolt fitted to hearings in the horizontal sections of the shipper-fork Oin a vertical position and having secured thereon the collar 1), between which and the lower horizontal section of said shipper-fork said bolt is surrounded by the spring q, the tension of which presses said bolt upward into contact with the clutch member N, as shown in Fig. 2.

The bolt R is acted upon by the cam-surface m, formed upon the clutch member N, to move said shipper-fork O and its rod 0" toward the right of Fig. 2 against the tension of the spring P, thereby disengaging the clutch member N from the member N, so that the gear E and clutch member N may revolve freely upon the shaft F, while the motion of said shaft is arrested by the shoulders on the clutch member N coming in contact with said bolt R and is locked in said arrested position by the bolt B being pressed into the socket 071 in said clutch member N.

The bolt R is connected bya wire or other suitable means to a treadle upon the floor, but not shown, by depressing which to a sufficient extent to move the upper end of the bolt R below the periphery of the cam portion of the clutch member N the tension of the spring P will cause the clutch members to be engaged and the shaft F to be revolved.

The right-hand arm I has secured thereto a block 0-, provided with a forwardly-projecting pin 7", upon which is adjustably secured the gage T and said block 0' also has set therein the bent rod r upon the end of which is adj ustably secured the gage r and the left-hand arm I has secured thereto the block t, provided with the pin t, upon which is adj ustably secured the gage t and said block also has secured therein the bent rod [5 upon which is adjustably secured the gage 15 as shown in Figs. 1, 2, 3, and 4:.

It will be observed that the tool-carrying arms I and J may be readily adjusted endwise, so as to adapt the positions of the several punches and their anvil-blocks to any particular curve of the shoe or boot quarter, and by a proper adjustment of the plate L the front end of the said arms I and J may be moved toward or from each other to vary the distance between the several punches.

The machine illustrated in the drawiu gs contains four pairs of punchingarms ar ranged to punch four holes in a boot-quarter at equal distances from each other and from the curved edge of the boot-quarter, and the gages r 1', t and i may be independently adjusted to properly locate the boot-quarter between the punching-tools. I do not wish, however, to be limited to the precise number of punching-tools or operating-bars herein described, and shown in the drawings, as it is obvious that the number of pairs of arms I and J may be increased to adapt the machine to punch a greater number of holes without departing from the principles of my invention.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a gang-punch the combination of a plurality of pairs of tool-carrying arms, each pair pivoted together at their rear ends, and independently pivoted to and adjustable endwise upon a common support; and means for adjusting the tool-carrying ends of said arms to a greater or less distance apart at one operation.
